WHAT: Find live music and theater events happening in your city each night, generally at a 50% discount. WillCall [ @Willcall ] only lists events in San Francisco right now. In beta, will be available as iPhone app. Expanding to New York and Los Angeles next.

INSPIRATION: "There are great shows going on every night – and I was missing all of them," Donnie told LAUNCH via email. "This wasn't an app problem or a pricing problem; it was an experience problem. We found that people habitually make casual evening plans at the last minute. With this in mind, we set out to create a service that empathizes with consumers and provides a unique experience to catching live events."
